Are time 1 and 2 consistent vs. stock assessment?
Do gains compensate for losses? Can gain substitute to losses?
Has the quality of the stock been maintained?
Gain in stock
e.g. by storage
Data Time unit
Data content issue
Loss of stock
e.g. by usage
Catchment statistical unit
The high differences between reaches demonstrates the need for considering river segment as SU
Essential: cannot be modelled
Replaceable: can be modelled from other variable
Define accurately statistical units
These three data sets are built from totally independent sources
Urgent progresses to make under SEIS,
Thank you for your attention
The problem with this source is that it presents only an area where irrigation could be done per cell (5’*5’). This gives a certain potential, to model with crops
Assumptions to be carried out in the accounting computation.
For refined computation, in the absence of other source, apportionment of JRC source (as volume per 10*10km cell) was used after apportioning per sub-basin, which is the smaller aggregation level (sub-basins are apportionment of RBDs).
Secondary assumption were made to share surface /GW and seasonalise.
